Abstract: A photographic element containing a silver halide emulsion layer having associated therewith, a dye-forming coupler and a dye stabilizer which has a melting point of less than 150.degree. C. (and preferably less than 100.degree. C.) and is of the formula: ##STR1## wherein R, m, q, X, Y, r, and (R.sup.7).sub.n are defined in the specification.The element particularly contains a coupler which forms a yellow dye upon reaction with oxidized developer. A method of making stabilizers of the above type using particular solvents and a non-aqueous workup, is also provided.

Abstract: Disclosed are curable compositions based on a combination of polyphenylene oxide, monomeric epoxy resin, a compatibilizing metal salt of tin, and suitable curing agents. The monomeric epoxy resin comprises a polyepoxide composition comprising at least one bisphenol polyglycidyl ether having an average of at most one aliphatic hydroxy group per molecule. The composition may be used in the preparation of laminates useful as printed circuit boards.

Abstract: The present invention is directed to a metal-clad electrical laminate which comprises a core of one or more of a polyetherimide thermoplastic, polyphenylene oxide thermoplastic, or a resinous-filled reinforced substrate. A pair of intermediate layers of hollow glass microsphere-filled polyphenylene oxide/epoxy is bound to either side of the core. Finally, a pair of metal foil layers are bound to the filled intermediate layers to produce the laminate of the present invention. The laminate desirably has a thickness of less than about 0.010 in., a dielectric constant of about 3 or less, and a HGM content in excess of about 10 wt-%. Additionally, the laminate has a softening point sufficiently high to avoid substantial distortion at processing temperatures of around 200.degree.-235.degree. C.
